How To Dial a Phone Number From a Webpage on an iPhone or Android Device

I always find it a ball ache when I am on a mobile device, see a telephone number on a webpage but it's not clickable to automatically dial the number for me. So if you need to do this on your websites, set up the anchor element as such:

<a href="tel:01234 567 8910">01234 567 8910</a>

Jobs dones! Nice and simple :)
